GTX780M Drivers Not Working/Detected

Hi,

I just got an iBuyPower CZ-27(which is a modified MSI GT70 with ibuypower touches and there were no other categories to put this in) laptop with a 780m today with all the drivers preinstalled. The first thing I did was to try and open the NVIDIA control panel to try to set some settings. A message box came up saying NVIDIA display settings weren't available. I'm like ok, maybe I need to be playing a game first so it switches graphics cards since its probably running on the Intel HD 4600 graphics right now. I open up Bioshock Infinite to see if it would fix the problem, but the control panel still wouldn't open. Not only that, it was still using the Intel HD 4600. I tested with League of Legends and I got 30 fps only on high settings with only the shadows being set to low.

I then open up my device manager and go to display adapters, while running a game, and I see the Intel HD Graphics 4600 along with GeForce GTX780m with a yellow warning sign. I tried tinkering further with it to no avail, and in the end I decided to reinstall windows 8 as a last resort.

Once I finished reinstalling windows 8, I tried reinstalling all the drivers that came on the cd. One driver couldn't install though, which were the NVIDIA ones. It kept saying that it couldn't detect the hardware so it wouldn't install. I went to device manager, and under display adapters, there was only Intel HD Graphics 4600 under it. I then tried to disable that to see if it would work; once I disabled it, a second thing came up which was Microsoft Basic Display Adapter with a the yellow exclamation warning. I tried to install the NVIDIA drivers after, and it worked. After restarting, I tried to open the NVIDIA control panel again, and a message box comes up saying NVIDIA display settings not available, You are not currently using a display attached to a NVIDIA gpu. I go to device manager and still see Microsoft Display Adapter.

(EDIT - I right click and it says Code 31.)

(EDIT2 - I disabled Windows Driver Signing. It changed to Geforce GTX 780M. I installed my drivers again and restarted, now it has disappeared from Display Adapters in my device manager.)

(EDIT3 - I go to properties on 780m and it says code 12. http://i.imgur.com/kn03DGL.png )

This is the point I got up to and now I'm stuck with what to do next. Please help.

Uninstall both HD4600 graphics and NVIDIA driver.

After restart, then try install Intel graphics HD4600 driver first and restart again.

If your Intel HD4600 working, no exclamation warning, continue install this 326.41 driver then restart

When the intel hd graphics was enabled, I couldn't even get the drivers to install because it didn't detect any gpu. I had to disable the intel graphics driver so the basic display adapter would show up, then the drivers would start. After I restarted and they were installed, the control panel still wouldn't open, saying an Nvidia Graphics card was no detected in my system. Not sure what I should do.
